any plan for this ?

[danvy]

@vthinkxie Any chance to get this PR approved ?

[simplejason]

I'm not sure if this is releated to the PR(#7626), if both of them solve the same problem, I will only merge one of the two PRs

[sebcam]

@simplejason, indeed, it seems to solve the same problem.

I close this PR since #7626 has been merged, if there still has the same bug, we need to create a new PR to fix it.
